[gentoo-user] two glibcs with different version

[Kraus Philipp]

Hello,

I must test a software with a older version of the glibc. I run the  
2.11.1 now but for one tool I need a previous version (2.6.1).
How can I compile the glibc without changing my system glibc. I would  
like to set the previous glibc with the LD_PATH.
Can I run two different versions or is a better solution to downgrade  
the system glib?

Thanks

Phil
